John Sutherand has won the 2007 Otago Chess Club championship, adding to his titles in 1999, 1997 and 1995. Returning to the club this year after several years working in England, Sutherland secured outright first place in the A grade with an unbeaten aggregate score of 9½/10. Second place will go to Quentin Johnson on 7½/9 with one game remaining while Hamish Gold's 5½/10 takes third place.
The B Grade championship was shared this year under the aggregate rules with Terry Duffield and Chris Lydiate both finishing on 6/9 ahead of Anthony Ritchie on 4½ in third place.
Today's game is from the A grade and features an accurate exploitation of advantage by the new champion, playing White against Duncan Watts.

A stock position in the Queen's Gambit Accepted has been reached, with many choices for White. The move chosen should allow Black enough freedom to equalise. 11. e4 cxd4 12. Nxd4 Nxd4 13. Rxd4 e5 14. Rd1 Bg4 15. f3 Bc5+?!
Equality was available in making use of the exposed White bishop with 15 ... Rac8 16 Nd5 Nxd5 17 Bxd5 Bc5+ 18 Be3 Bd7. 16. Kh1 Be6
Black accepts the weak doubled pawns in order to stay active and with hopes of a king-side counter attack using the opened f-file. 17. Bxe6 fxe6 18. Qc4 Qe7 19. Bg5 Rac8 20. Qb3 h6 21. Bh4 g5!?

Both players miss some tricky resources: 33... Rg7+! 34 Bg3 Nd7 holds all the Black pawns and White could have won a pawn by 33 Ra8! when if a5 then 34 Nf4 picking up the e6 pawn. The balance of the game is not significantly altered. 34. Bd4 Bxd4 35. Nxd4 Rd7?!
Activating the rook but still 35 ... Nd7 36 Re8 e5, defending all the pawns held better chances. White's central passed pawns combined with rook and knight are a dangerous attacking force. 36. Nxe6 Rd2+ 37. Kg3 Rxb2 38. Rb7+ Kg8 39. h3 Rb3 40. e5 Ne8? 41. Re7 b5

Triumphant return for Sutherland
Problem: White to play and mate in four.
